Antonio Mannino's research focuses on studying the distributions, sources and sinks of dissolved (DOM) and particulate organic matter (POM) in the ocean to enhance our understanding of carbon cycling, especially in the coastal zone. A primary objective is to link the optical properties of DOM and POM (such as absorption, scattering and fluorescence) to carbon in the ocean to be able to examine the carbon cycle using ocean color satellite measurements. Dissolved organic carbon (DOC) comprises nearly all (>97%) of the organic carbon in the ocean and constitutes one of the largest pools of organic carbon in the biosphere (equivalent to carbon dioxide in the atmosphere). Studying the distribution, sources and sinks of DOC and particulate carbon within the ocean is essential to understanding the Earth and ecosystem variability.
